. :UNITED s'rarrf CULTIVATOR SHIELD.

:To all whom'it may concern .Be it known that'I, OLAF B KosMALsKI,

a citizencof the United States of America,

residing at Taunton, in the county of Lyon and State of Minnesota, have invented cerf tain new'and useful; Improvements in G111,- tivator Shields, of which the following is-a specification,

This inventionrelates to certain new and useful improvements in cultivator shields of that typeiwhich are Jintendedto be attached to cultivators of the straddle rowtype for rendering the cultivating operation more eflicient, I j

The primary object of the-'present inven tion is to provide an improved shield of this kind so constructed as to effectively cause lumps of soil to be thrown between the planted rows whileat the same time allowing substantially all ofthe fine dirt to be moved against the plant. t

A further object of the invention is to pro vide a shield of this kind which will eflec- "tively raise fallen plants for permitting the dirt to be thrownparound therootsthereof so that the plants will bebraced'in upright position and whereby covering of the plants with earth is prevented.

A still further object of the invention is the provision of. an adjustable mounting means fora cultivator shield, by means of which the 'shie'ldmay be regulated, for being most effective in accordance with the height of the plants being cultivated and regardless of the lumpy or finer nature of the soil,

Still another object of the invention is to provide a cultivator shield including a guard member pivotallymounted so as to be allowed to yield upwardly so as to avoid damage thereto when passing over lumpy places ence characters designate corresponding parts throughout the several views,

Referring more in detail to the several v1ews,-the present invention contel'nplat es the prov slon of a shield including a bar; 5

adapted to assume'a substantially horizon- '1 tal position besidethe shovels 6 ofthec-cultivator bars 7 when in use and .havinga plurality of spaced depending fingers 8-'attached thereto, The fingers 8 extend later- .ally from the bar 5 and are of inwardly curved form as well as being arranged sufficiently close together as to effectively act-as a screen for preventing lumps of dirt from being thrown onto the of shields. In other words, these fingers insure throwing of thelumpsof soil between the PlHlItBd l OWSV The forward end portion of the bar 5 is I provided with a perforation 9 for reception of one end of a yieldable member 10 which is preferably in the form of a helical spring,

and which has its other end attached to an eye on the adjacent end of a guard member .11. The guard ll is preferably in the form of a stout and slightly resilient wire which is curved downwardly and forwardly and then bent upon itself to extend. rearwardly plants between a pair.

alongside of and beyond the fingers S'as shown in Figure 1. This rearwardly extending portion ofthe guard is so arranged to effectively ride under the fallen plants as well as the drooping leaves of the plants.

for raising them upon continued outward movement of the cultivator, and another member 12 having a similar 11111013101118 welded or. otherwise secured as at-13 to the forward portion of the guard 11 and extends rearwardly above andparallel with the said rearwardly extending portion of the guard 11. 7 Obviously, when the pl a-ntsare thus raised, they will be held raised while the shovels'of the cultivator throw the fine *dirt between the fingers and the parallel portions of members 11 and 12 and against the plants and while said fingers prevent the large p lumps from beingso thrown or cause said "lumps to fall between the planted rows.

A pivoted member or bracket 14 is mounted for longitudinal tilting movement on the bar 5 as at 15, and this bracket is provided with beads 16 in which the adjacent portions of the guardll are secured as shown in Figures 1 and 2, and a stopmember 17 is fastened to the bar 5 between it and the bracket 14 by riveting or the like so that the lug'18 of said stop is arranged to limit the tilting movement of the bracket l tinone direction so as to insure against the forward end of the guard 11 being tilted downwardly belike.

Means is providedifor adjustably mounting the shield upon the inner cultivator bar of the cultivator as shown in Figure 2,

. wherein two shields are illustrated in spaced mounting means relation with the fingers '8 extending inwardly and downwardly toward each other at opposite sides'of the planted'row. This includes an attaching clamp composed of the member 20 of Figure 6 and the member 21 of Figure 7 adapted to be bolted against the opposite side faces of the cultivator bar 7 and to each other by bolts 22 passing through the perforations 23 of said members 20 and 21 behind and in front of the bars 7 The clamp member 20 is provided with a forwardly. and downwardly inclined end portion 2 1 having an aperture at 25 in the lower end thereof adapted to register with the aperture 26' of the upwardly extending portion 27 provided on the rear end of a bracket member 28, and a bolt 24; is passed through said apertures 25 and 26 for fastening the members 20 and 28 together and for securing the bracket 28 in various tilted positions as illustrated by dotted and full lines in Figure 1 and for a purpose which will come apparent. V

V The bracket member28 is in the form of a strip of metal extending forwardlyin a substantially horizontal position and having a plurality of spaced perforations 29 adapted to be selectively alined with the aperture 30 of the upwardly extending lug 31 provided presently beon the rear end portion of the guard carrying bar 5. When the aperture 30. has been alined with the desired one of the apertures 29 so that the shield is properly positioned forwardly or rearwardly relative to the adjacent cultivator shovel 6, it is fastened in such position by a bolt 32 passing through the alined perforations 29=and30 "If the plants being cultivated are sufficientlytall, the cultivator shield may be found to operate to better advantage if the shield is tilted I upwardly at its forward end as shown'l' by dotted lines in Figure 1, andthis may be done by swinging the shield about thebolt 24 as a pivot. If a further adjustment is required, the entire structure may be adjusted upwardly upon the cultivator bar 7 by looseningthe'bolts 22 of the attaching clamp. These tilting and longitudinal adjustments together with the longitudinal tilting of the guard relative to the fingers insure effective operation of the shield under the many and various conditions met'in cultivating. j I s From the foregoing description, it is be lieved that the construction and operation of the present invention will be readily understood by those skilled in the art.

Minor changes may be made in the details of the construction. without departing from the spirit and scope of the invention. WVhat is claimed as'new is: v 1. A cultivator shield of the class. described comprising a plant l'ifting'guard-,'a carrying member for said guard,"depending fingers carried by the guard carrying member arranged at the rear portionof the guard and positioned in spaced relation for preventing-lumps of dirt from being thrown on the plants While permitting the finer dirt to be moved up against the plants, a mounting bracket adapted to beclamped to the bar of a cultivator and including a substantially horizontal strip portion" with spaced apertures, an upstandinglug upon 2. A cultivator shield of the class described comprising a plant lifter guard, a carrying member for said guard, an inverted U-shaped bracket pivoted to said carrying member and having beads upon its ends, said guard including a wire member having its uppermost end'journaled within the beads for said guard.

3. A cultivator shield of the class described comprising a plant lifting guard, a-

carrying member for said guard, an inverted U-shaped bracket pivoted to said carrying member and having beads upon its 10 ends, said guard including a wire member having its uppermost end journa'led Within the beads of. the said pivoted bracket, spring connecting means between the extreme end of said W1re member and the carrylng mem-' her for said guard, and a stop bar upon the 15 carrying member for limiting the pivotal movement of said U -shaped-bracket and' plant lifting guard. i

In testimony whereof I aflix my signature.
